The user who has previously released an RPi OC version for Innosilicon A2 miners that did not work properly due to the fact that the official cgminer provided only accepted a few fixed operating frequencies has updated the image to version 2.0 and now it works. The new version adds support for 1000 MHz and then from 1080 MHz to 1400 MHz in 20 MHz steps and now the cgminer accepts these values due to a modification done to the A2 driver. So if you are an owner of an A2-based miner using 28nm Innosilicon Scrypt ASIC chips you might want to try the image out, we have already checked it and can confirm it works well.

Something very interesting for the people with Innosilicon A2-based Scrypt ASIC miners, a Raspberry Pi image based on the original Innosilicon web-based interface, but with much more options for setting the operating frequency of the miner. This release by a user called Emdje should be compatible with both the smaller and the large A2 Scrypt ASIC miners allowing the users to set the operating frequency of the chip boards available between 1200 MHz and 1330 MHz, in increments of 5 MHz. This allows for some fine tuning to reach better performance balancing the performance and HW error rate optimally for your own mining hardware, as the default RPi image for the A2 miners from Innisilicon limits you to either 1000 MHz or 1200 MHz setting for the frequency. And an operating frequency of more than 1200 MHz with no significant increase in the number of HW errors is easily achievable as these A2-based miners are operating very cool and can be pushed some more. And who would not wan to get some extra hashrate from the existing mining hardware…
